'Switched at Birth' season 5 episode 3 spoilers: Lily to call off wedding? Regina thinks about introducing her new boyfriend

Toby (Lucas Grabeel) and Lily (Rachel Shenton) get into a big fight, and the latter might call off the wedding. Meanwhile, Regina (Constance Marie) is worrying about whether she should introduce her new boyfriend to the family.

On the upcoming fourth episode of "Switched at Birth" season 5, titled "Surprise," The happy couple will be coming home along with their baby for a visit, and they will let everyone know of their wedding plans. However, it seems that Toby and Lily will run into a huge conflict minutes before they tie the knot.

The synopsis for the episode reads as follows: "Returning from London for a visit, Toby and Lily reveal their plans to get married in the Kennish backyard. But a fight before the wedding may tear them apart before they can say 'I do.' Regina must decide whether to reveal her relationship with Luca to the family. When she least expects it, Bay runs into Tank (Max Adler) again."

As seen from the episode promo, Toby tries to convince Lily that he's eager to spend the rest of his life with her. However, angry and unconvinced, Lily walks away from Toby while wearing her wedding gown and while holding her bouquet.

Meanwhile, Regina will be thinking about introducing her new boyfriend to the family.

Regina's new love interest is portrayed by Michael Galante, and according to executive producer Lizzy Weiss, this is someone that Regina rebounds to from her serious relationship with Eric (Terrell Tilford).

During an interview with TVLine, Weiss explained, "We just really wanted to lighten things up for her and be honest. ... It would probably be something a lot less serious and fraught and intense than what she had with Eric."

"Switched at Birth" season 5 airs every Tuesday night at 9 p.m. ET on Freeform.
